Specific implementation mode
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1, in embodiment 1, a kind of smart lock unlocking opportunity judgement based on sound field movement and apart from detection
Method, wherein step S01 are initialization step, and step S02~S05 is unlocking opportunity judgment step；Specifically include following steps：
S01：The first sound wave generating device is set in unlocking terminal, while the first sound wave can be received in smart lock setting
First acoustic receiver device of the first sound wave of the particular community that generating means is sent；Specifically, the particular community includes
The first sound wave of particular community can be identified in specific frequency and/or specific waveforms feature, smart lock.
S02：Unlocking terminal sends the first sound wave of particular community by the first sound wave generating device；Specifically, this first
Sound wave can repeatedly be sent with certain frequency to the first sound wave generating device, and the smart lock later stage is facilitated to judge mobile status, and be somebody's turn to do
Certain frequency is presupposed solution.
S03：Smart lock receives the external sound wave sent by the first acoustic receiver device, and determines whether described specific
First sound wave of attribute, if yes then enter step S04, otherwise return to step S03；Specifically, smart lock can pass through judgement
Whether the external acoustic waves received are specific frequency and/or specific waveforms feature, to judge whether it is the of particular community
One sound wave, S04 is entered step when being judged as the first sound wave.
S04：First sound wave of the particular community to receiving is detected, and judges the position of unlocking terminal, and will be multiple
The position of the obtained unlocking terminal judged is combined the mobile status to form unlocking terminal.
S05：According to the position and movement state of the obtained unlocking terminals of step S04, with the unlocking shift strategy that prestores into
Row adaptation, the precondition as unlocking operation.Such as：(1) when the position of unlocking terminal always apart from smart lock farther out, then after
The unlocking operation of phase does not execute；(2) it is more and more closer at a distance from smart lock to work as unlocking terminal, and has been finally reached predetermined low level
When, then the unlocking operation in later stage starts to execute；(3) it is more and more closer at a distance from smart lock to work as unlocking terminal, but not up to pre-
If when low value, later stage unlocking operation does not execute.The unlocking operation includes but not limited to that smart lock obtains the transmission of unlocking terminal
Sound wave password judge it unlocking authority identifying procedure for carrying out unlocking etc. again.
Using such mode can solution never have the unlocking opportunity judgement method present in following Railway Projects：1、
Unlocking terminal does not reach door lock beside door lock and may but open；Although 2, unlocking terminal reaches near door lock, door lock can not be sentenced
The problem of fixed suitable unlocking opportunity, i.e. user, hold unlocking terminal and reach door lock nearby but do not prepare to unlock, and door lock is but opened
The problem of.
And in example 2, as shown in Fig. 2, a kind of smart lock based on sound field movement and apart from detection is unlocked, opportunity is sentenced
Determine method, wherein step S01 is initialization step, and step S02~S05 is unlocking opportunity judgment step；Specifically include following step
Suddenly：
S01：The first sound wave generating device is set in unlocking terminal, while the first sound wave can be received in smart lock setting
First acoustic receiver device of the first sound wave of the particular community that generating means is sent；In addition, the second sound wave is arranged in smart lock
Generating means, and the particular community of the second sound wave generating device transmission can be received in a certain range in the setting of unlocking terminal
The second sound wave rising tone wave receiving device.It is similar to Example 1, the particular community include specific frequency and/or
Specific waveforms feature, the first sound wave of particular community can be identified in smart lock, and unlocking terminal can be to particular community
The second sound wave be identified.
S02：Smart lock sends the second sound wave of particular community by the second sound wave generating device, in described a certain range
Unlocking terminal when receiving the second sound wave of the particular community by rising tone wave receiving device, pass through the first sound wave and occur
Device sends the first sound wave of particular community.Specifically, in the present embodiment, smart lock wakes up unlocking by sending the second sound wave
The mode of operation of terminal, the unlocking terminal after wake-up is similar to Example 1.Furthermore it is preferred that between the transmission of each second sound wave
Every sending the first sound wave to the time span of smart lock, the hair after maximum magnitude receives the second sound wave not less than unlocking terminal
It is presupposed solution to send interval also.
S03：Smart lock receives the external sound wave sent by the first acoustic receiver device, and determines whether described specific
First sound wave of attribute, if yes then enter step S04, otherwise return to step S03.Similar to Example 1, smart lock can be with
By judging whether the external acoustic waves received are specific frequency and/or specific waveforms feature, to judge whether it is specific
First sound wave of attribute, S04 is entered step when being judged as the first sound wave.
S04：First sound wave of the particular community to receiving is detected, and judges the position of unlocking terminal, and will be multiple
The position of the obtained unlocking terminal judged is combined the mobile status to form unlocking terminal；
S05：According to the position and movement state of the obtained unlocking terminals of step S04, with the unlocking shift strategy that prestores into
Row adaptation, the precondition as unlocking operation.Unlocking shift strategy is similar with being enumerated in embodiment 1, herein without superfluous
It states.
Specifically, for the mobile status, including simple distance change and actual change in location, for list
Pure distance change only needs that a first acoustic receiver device is arranged；And for needing then to need actual change in location
Multiple first acoustic receiver devices are set at the different location of smart lock, and specifically, each acoustic receiver device calculates
Go out a unlocking terminal and smart lock distance r, and is r by original point structure radius of the position of each first acoustic receiver device
Sphere, the common crosspoint of multiple spheres is physical location, and multiple physical location is added up, and is obtained actual
Change in location.
More preferably, the first sound wave of the particular community to receiving in step S04 is detected, is may be used unlimited
It is realized in following three kinds of modes：
First way, while being suitable for embodiment 1 and embodiment 2, specifically include following sub-step：
S0411：Obtain the reception power P R of the first sound wave of the particular community received；

Defeated rate is identical with the transmission rate of the second sound wave；It can also be to smart lock or smart lock external temp detection module and built-in
Transmission rate computing module calculates the transmission rate of the first sound wave or the second sound wave according to real time temperature.
And for step S0431, since the transmission of the second sound wave and the reception of the first sound wave are realized on smart lock, because
This only need on smart lock built-in time module, but need to ensure the precision of the time module.
In any one above-mentioned embodiment, the unlocking terminal is intelligent mobile mobile phone/tablet computer etc..For reality
Apply example 1, when need unlocking terminal send the first sound wave when, by APP open Active Unlocking pattern, at this time unlocking terminal start by
The first sound wave is sent according to certain frequency；And for embodiment 2, APP opens passive unlocking pattern, and unlocking terminal passively receives at this time
After to the second sound wave the first sound wave is sent to smart lock.
